Embodiment Construction

[0041]A yarn state detection device 100 according to an embodiment of the present invention will be described with reference to the drawings. The yarn state detection device 100 is applied to the textile machine 200, and optically detects the state of the running yarn Y. The state of the yarn Y refers to the thickness (apparent thickness) and / or the presence or absence of impurities. The textile machine 200 to which the yarn state detection device 100 is applied is not particularly limited. For example, it can be applied to an automatic winder or an air spinning machine. It can also be applied to textile machines 200 other than automatic winders or air spinning machines. In addition, it can also be applied to an inspection device that optically inspects the state of a running yarn.

[0042] figure 1 The yarn state detection device 100 arranged along the running path of the yarn Y is shown. figure 2 A cross section of the yarn state detection device 100 cut along a direct...

Abstract

The invention relates to a strand state detection method and a strand state detection device. The strand state detection device (100) comprises: a light-casting part (21) for irradiating light to an advancing space (13) of a strand (Y); a light-casting surfacve (32) for the light irradiated from the light-casting part to enter the advancing space; a light-receiving surface (33) of an exit surface being irradiated from the light-casting part and passing through the advancing space coming out from the advancing space; a first light-receiving part (41) of the light passing through the advancing space; a second light-receiving part (51) being irradiated from the light-casting part and not passing through the advancing space; and a control part (61) for controlling a control value driven by the light-casting part. The control part (61) determines ensured processing changed in a main reason of the first light-receiving part and the second light-receiving part according to light receiving amount of the first light-receiving part and the second light-receiving part.

Description

technical field [0001] The present invention relates to the technology of a yarn state detection method and a yarn state detection device for optically detecting the state of a traveling yarn. Background technique [0002] In the production stage of the yarn, impurities may be contained in the yarn. In addition, the thickness (apparent thickness) of the thread may not be substantially constant. In the case where impurities are contained in the yarn and / or when the thickness is not substantially constant, the quality of the yarn will be reduced. [0003] Conventionally, there is known a yarn state detection device that optically detects the state of the yarn, such as the thickness of the yarn and / or the presence or absence of impurities. The yarn state detection device is to install a light projecting unit (light source) and a light receiving unit around the running space where the yarn is arranged, and to monitor the thickness of the yarn and / or the presence or absence of ...
